The function and purpose of Coolant & Radiator Hose.

Engines need to keep cool if they are to maintain operational status. That's why your Pontiac Bonneville engine has a network of cooling hoses transferring a mixture of water and ethylene glycol throughout the engine. The radiator hoses under your hood connect the water pump and engine block to the radiator core, while other coolant hoses send the ethylene glycol mixture through the thermostat, return the coolant to the expansion tank, or by-pass the heater hose flange. If a Pontiac Bonneville radiator or coolant hose springs a leak, then your engine will lose its ability to maintain the prescribed operating temperature; leading to engine failure.
